HANDLING CHIP COMPONENTS

1-6

GB

All ICs and many other semi-conductors are susceptible to electrostatic discharges (ESD). Careless handling during repair can reduce life drastically. When repairing, make sure that you are connected with the same potential as the mass of the set via a wrist wrap with resistance. Keep components and tools also at this potential.

Tous les IC et beaucoup d’autres semi-conducteurs sont sensibles aux décharges statiques (ESD). Leur longévité pourrait être considérablement écourtée par le fait qu’aucune précaution n’est prise à leur manipulation. Lors de réparations, s’assurer de bien être relié au même potentiel que la masse de l’appareil et enfiler le bracelet serti d’une résistance de sécurité. Veiller à ce que les composants ainsi que les outils que l’on utilise soient également à ce potentiel.

WARNUNG

Alle ICs und viele andere Halbleiter sind empfindlich gegenüber elektrostatischen Entladungen (ESD). Unsorgfältige Behandlung im Reparaturfall kan die Lebensdauer drastisch reduzieren. Veranlassen Sie, dass Sie im Reparaturfall über ein Pulsarmband mit Widerstand verbunden sind mit dem gleichen Potential wie die Masse des Gerätes. Bauteile und Hilfsmittel auch auf dieses gleiche Potential halten.

ESD PROTECTION EQUIPMENT:

NL

Alle IC’s en vele andere halfgeleiders zijn gevoelig voor electrostatische ontladingen (ESD). Onzorgvuldig behandelen tijdens reparatie kan de levensduur drastisch doen verminderen. Zorg ervoor dat u tijdens reparatie via een polsband met weerstand verbonden bent met hetzelfde potentiaal als de massa van het apparaat. Houd componenten en hulpmiddelen ook op ditzelfde potentiaal.

Tutti IC e parecchi semi-conduttori sono sensibili alle scariche statiche (ESD). La loro longevità potrebbe essere fortemente ridatta in caso di non osservazione della più grande cauzione alla loro manipolazione. Durante le riparazioni occorre quindi essere collegato allo stesso potenziale che quello della massa dell’apparecchio tramite un braccialetto a resistenza. Assicurarsi che i componenti e anche gli utensili con quali si lavora siano anche a questo potenziale.

<9> <9> <9> <9> <AUDIO> <6> ...........for LX3950W/05

4) The display shows 'YYYY-ZZ' and the tray will close.

YYYY = model number (eg. 3900, 3950, etc.) ZZ = stroke version (eg. 01, 05, etc.)

Procedure for check Software version

1) Power up the set and select DISC source.

2) Open tray by press "OPEN/CLOSE" button on the set or press and hold "STOP" button on the RC.

3) Press "OSD" button on the Remote control.

Procedure to upgrade software

1) Power up the set and select DISC source.

2) Open tray by press "OPEN/CLOSE" button on the set or press and hold "STOP" button on the RC.

3) Place upgrade CD-ROM onto tray and close.

4) The set will response and display the following:

- LOAD [After the disc is read, the tray will open for you to remove the disc]

- ERASE

- WRITE

- ERROR [if upgrade is unsuccessful]

- UPG END -> PHILIPS [if upgrade is successful]

- DISC->CLOSE->LOAD [Tray will close indicating that the upgrade process is completed]

5) The whole process should not take more than 5 minutes.

Caution: Do not unplug the set until upgrade is completed.

Trade Mode

Trade mode is a feature that will block all set keys when enabled. It is for dealers to prevent customers from removing disc, changing source etc using the set keys. Rotary and Remote Control (RC) keys are still allowed in Trade mode.

AV BOARD

BRIEF INTRODUCTION OF THE AV BOARD

The AV Board consists of the following features :

a. IC CS42418

IC CS42418 which includes functions such as ADC and DAC, sound control, volume control and muting function. Sound features such as DSC are controllable via I2C Bus from the SD6.1 module.

The IC caters for 2 channels analog input via a 4 stereo channels MUX HEF4052BT. The MUX multiplexed between Aux In, TV In, Tuner and Mic In. Input networks are included to provide appropriate attenuation for various sources.

b.

SCART (for /01 and /05 versions only) SCART input/output for audo/video (output only) connection to TV.

c. LINE OUT

Line out with cinch socket for connection to external amplifier.
